The main obiecls ot this ii'rfention are to simplify. strenrrnien and iingn'eve structures nl this Class; to taf-ilitutv their nation. to produce substnntially llat ceilings. in .so arrange the instal rein'ff'oicingl' bars or l. floors and ceilings as te talus my reversal of moment and with tl rein'lif'rieii'ig bers or rods in the louer barisoi." the lwauis to atford the Wind bizieinf required in high buildings; to avoid tln` necessity et' bending` the reinforcing bui's or rolls event those el small Size or section uhiehlvan he readily bentas the). rile-.eed in the s'ruifture.' and to adi of the eiimlownenf. in 'the 'torni Work ol such standiird di isnf oi lumber as will not be easily brol in handling and may1 therefore be used over and over again indefinitely.

These rods being ot comparativehT small seetion er'sifie, are readihr` bent as'tlie)7 are placed in position. and Serve when the strueture is complete. to bind the Column members oi3 the entire structure together. Toward the ends where the)Y are bent around the bars n., they are brought te the upper part of the panels or horizontal slabs supported b v the columns and their obliquely bent ends radiating from the columns are inclined downward so as to take the moment produced in the. eantalirers, indicated by dotted lines in Fig: Q. 0n the ends of the tie rods c', radiating: from the several coluinns into the corners of the adjoining panels, are placed supporting rods d, one of which is shown b V itself in Fig. 4, te afford bearings for and ea'rrv reinforcing rods spanning the panels diagonally and parallel with the beams in the upper part of the slabs adjacent to the corners ofthe panels, .as hereinafter explained. These supportare arranged as oling bars are bent as shown, to the form of a square or otherwise, so as to surround the columns at a distance therefrom, one or more being placed around each column, and they are bent inwardly and lapped at the ends where they are brought together. Across the tie rods con two opposite sides of each panel, and across the rods d adjacent to their ends, are then laid at suitable intervals, parallel with the tie rods c on the other two sides of the panel, reinforcing rods e. In like manner, across the rods e are laid at corresponding intervals, reinforcing rods f, and then upon the rods e and f are laid two sets'of'diagonal rods g and h, the several rods e, f, 'g and spanning the several panels and being brought adjacent to the corners of the panels into the upper part of the concrete floor and ceiling slabs, where they are supported by the rods d resting ou the tie rods c and their inwardly and obliquely bent ends in position, to take the,V rnbrellareversal of moment to which the u like cantaliver structures at the corners of the panels are subjected. These rods e, f, ,c7 and L, are lapped ,vhen necessary, where they cross the tie rods c in or adjacent to the beams spanning the spaces between the columns. Rods z', running lengthwise throughthe lower part of the beams inside' of the vertical column bars a and below the tie rods c serve to strengthen the beams and in connection with the tie rods afford the wind bracing required in high buildings.

T he form work, which may consist mainly of lumber of such standard dimensions as will not be easily broken in handling, and may consequently be used again and again indefinitely, is built up as shown in Fig. 2, to produce molds for the columns and beams and a support for the panel slabs carried by the columns' and beams. As shown, Q-inch planks j, laid at suitable intervals on 4X4 inch stringers 7c, carry a floor l of boards or of plain or corrugated sheet metal, on which the horizontal panel slabs of the concrete structure are molded and supported till the concrete has set or hardened sufficiently to permit the removal of the form work. The stringers /c are supported at intervals by short 4x4 inch cross pieces lm., resting on vertical 4x4 inch struts or posts 'n and braced therefrom by diagonal strips 0. The beams are made of such a depth that lumber of standard dimensions, as for example, 4x4 inch pieces 79, may be used to form the sides which project below the ceiling or lower surface of the intervening panel slabs. These pieces are beveled on the sides next to the beams, so that they may be readily removed without disturbing the concrete, and they arev supported on 2-inch planks q, which form the bottoms of the molds for the beams. The planks g are supported at intervals, like the strngers k, on short 4x4 memos inch cross pieces m, carried by vertical struts .or posts n, from which they are braced in like manner by diagonal strips of wood o.

In Fig. 2, r designates the columns, s the beams and t the floor and ceiling slabs, the form Work being removed from the column at the right.

After the metal reinforcing structure has been arranged and the form work has been erected as above explained, the concrete is molded in the usual manner around the metal structure, and when it has set or hardened suiliciently to admit of it, the form work is removed. in condition for further use in the erection of similar structures.
